Vivisimo is set to announce this week an enterprise search engine that helps find patterns and topics within a document to return categorized results on the fly for each query.

Vivisimo's software, Velocity, runs on Linux servers and is targeted at companies or departments that need to index fewer than one million documents. Using the company's patented linguistic algorithms, the package crawls and indexes most standard formats, including HTML, Microsoft Office, PDF and PostScript.

Vivisimo is targeting the million-documents-or-less market with this product because an index of that size will fit on a standard server, says Raul Valdes-Perez, the company's CEO. For larger document repositories, Vivisimo sells its categorization and content integration technology separately and rides on top of existing search products such as those from Google and Verity.

Effyis, an Ann Arbor, Mich., company, is implementing Velocity to search Weblogs and Usenet Newsgroups for patterns and trends in human-to-human communication. It will use the integration piece to bring in empirical survey data to match how those results compare with what people are saying in Web postings. "Velocity can let us incorporate all these meta information pieces and then cluster all that," says Scott Purdon, COO of Effyis, which is the Greek word for clever.

Effyis' current offering at www.boardreader.com uses Vivisimo clustering to help users cull through the 1 million comments the search engine indexes each day.

Vivisimo's announcement comes on the heels of competitor Google's announcement of an upgraded enterprise search appliance aimed at larger users. Verity, Autonomy and Fast Search & Transfer also compete in this arena.

Velocity is scheduled for general availability in the next 30 days. Pricing starts at $10,000 per year, depending on the number of documents being indexed.
